Lenen Puma No. 94,803, daad september 14, 1869,

To all whom it may concern:

Be it known' that we, JOHN C. WILSON, ADAM WALKER, and JOHN FOSTER, allof the city, county, and State of New York, have. invented a new anduseful Improvement in Clipping-Shears, for clipping or shearing the hairof horses and other animals; and do hereby declare that the following isa general description thereof', reference being had to the accompanyingdrawings, making part of this specication, of which- Figure l is a topview of our improved clipping\ shears;

Figure 2, a longitudinal section of same;

Figure 3, an under side view of the upper serrated cutter, showingheel-spring, circular opening for passing the said plate over thelever-handle, with recesses for reception of double-toothed lever; and

Figure 4, a sectional view of said upper serrated cutter, showingheel-spring and set-screw.

The nature of our invention consists' in constructing a clipping-shearswith a double-'toothed lever for perat-ing the upper or movable serratedcutter, and the said cutter' with a spring heel-plate and set-screw, forclosing the cutters as they wear fromA use or .from sharpening; also, inproviding said movable cutter with an opening iu thel centre for passingthecutter over the lever-handle, when the cutter-blades may requiresharpening, while the lever lWhichoperates said cutter is firmlyattached to the lower cutter-blade; and also in connecting thecutting-blades near their serrated edges by means of slab-sidedscrew-bolts, washer, and nuts, which will not work loose, while theyallow the upper serrated cutter to slide freely back and forth on thelower or stationary serrated cutter.

In the said drawingsv A indicates the lower or. stationary serratedcutter, mounted with a handle, B.

C is the upper or movable serrated cutter attached to the stationarycutter by flattened orslab-sided bolts D, continuous washer or plate, E,and nuts F.

These bolts and nuts remain stationary and will not work loose, becauseof the bolts being slab-sided, while the upper cutter C, having slots cc, &c., slides freely back and forth.

G is the spring-heel plate, rmly secured to the upper cutter by livets hh and operated by a set-screw,

I, for the purpose of elevating the tail end of the y movable cutter, soas to adjust the serrated edges of the cutters in relation to eachother, should they become worn from use or from sharpening. K K are therecesses in the said movable cutter for reception of the double-toothedlever; and L i4 the circular opening, which admits (on remov- .iug thebolts and nuts) of passing the movable cutter over the leverhandle, whenit may be desired to sharpen the cutters, while the lever remainsfirmlyv attached to the stationary cutterl M is the double-toothedlever, of which N is the handle, said lever being firmly attached by arivet, O, to the stationary cutter and provided with teeth, p p,

which play into corresponding recesses K K, in the.

movable cutter, by meansof which the movable cutter' is slid back andforth on the stationary cutter and the clipping-operation performed. f

We are aware that Letters Patent, No. 84,926, dated December 15,1868,were issued to us for au improvement -in clipping-shears; butwe havefound from experience with this clipping-shears that it necessitatedfurther improvements to render its performance .perfect, inasmuch as theheel of the movable cutter B, in

, its movements, wore a channel in the shank A of the stationary cutter,on which it rested, causing the cutters to spread apart, whichl defectwas partially overcome for a time by bracing the plates together by thethumb set-screw L. But this operation retarded the movements 'of thesliding cutter, while the thumb set-screw itself worked loose, allowingthe cutters to spread apart. Besides this, the wear on the single toothD of the lever affected able cutter.

These defects in the original horse-clipper suggested to us ourimprovement, which'we find, from use of same, to'answer the desiredpurpose.

Having described our invention,

What we claim, and desire to secure by Letters Patent, is p Thedouble-toothed lever M, spring-'heel plate Gr, set-screw I, circularopening L, bolts D,and plate E, constructed, arranged, and operatingsubstantially as and for the purposesdescribed and Set forth.

In testimony whereof, we have hereunto set our signatures, this 9th dayof August, A. D. 1869.
